INNERSOLE. i

Specification of Letters Patent.

Patented Apr. 25, 1916.

Application led Tune 29, 1915. Serial No. 36,959.

To all 'whom t may concern Be it known that I, CONRAD B. MANSBACH, acitizen of the United States, and resident of Brockton, in the county ofPlymouth and State of Massachusetts, have invented certain new anduseful Improvements in Innersoles, of which the following is aspecication.

This invention relates to an inner sole composed of a body memberusually made of leather and a facing member usually made of textilefabric, such as duck or canvas, and provided with a raised rib extendingparallel with its margin and adapted to receive the inseam stitcheswhich unite the upper, welt, and inner sole of a'. welted shoe, said ribbeing usually formed by embossing the facing member.

The invention is embodied in certain improvements in the facing member,said improvements enabling said member to be made of relativelyinexpensive material, such as the waste or scraps left after cuttingsheet material into relatively large forms or blanks.

Of the accompanying drawings forming a part of this specification:Figure 1 represents a side view of a blank from which the facing memberembodying my invention may be cut; Fig. 2 represents an opposite sideview of the blank shown by Fig. 1, portions of the pieces forming thisside of the blank being broken away; Fig. 3 represents an edge view ofsaid blank; Fig. 4L represents a side view of a completed sole; Fig. 5represents a perspective view of a portion of the blank in the conditionshown by Figs. 1, 2 and 3; Fig. 6 represents a perspective view showinga portion 'of the blank molded to form a lip, the trimmed edgesubsequently formed being indicated by dotted lines; Fig.

7 represents a transverse section of a completed inner sole of which thefacing member shown by the preceding figures forms a part, the sectionbeing on the plane of line 7 7 of Fig. i; Fig. 8 represents a side viewof one of the pieces shown by Fig. 1.

The same reference characters indicate the same or similar parts in allthe views.

An inner sole of the class to which my invention relates is composed oftwo soleshaped members, viz., a body member a (Fig. 7) usually made froma single soleshaped piece of leather, and a facing member usually madefrom a single sole-shaped piece of duck o r canvas cmented to `one sideof the body member and embossed or molded to form a hollow rib extendingparallel with the shank and fore part edges, and constituting an inseamstitch-engaging lip. A sole of this character is shown in my applicationfor Letters Patent of the United States, filed March 31, 1915, SerialNumber 18,259.

My present improvement is intended to reduce the cost of the fabricfacing member of an inner sole of the character above described, andatthe same time increase its strength and durability and enable theshank portion of the facing member to be made thicker, if desired, thanthe heel and fore portions.

In carrying out my invention I preferably construct the facing member asfollows: From waste fragments trimmed from sheets of fabric I cutrelatively small pieces or sections 12 and 13, each preferably ofrectangular form and longer than the predetermined width of the facingmember, so that each piece extends transversely across the facingmember, the proportions of the said pieces being such that severalpieces are required to form a blank of suitable length to enable afacing member to be cut therefrom. The pieces are assembled to form anelongated blank, as shown by Figs. 1 and 2, a series of pieces 12constituting a layerforming the outer side, and a series of pieces 13constituting another layer forming the inner side of the blank. Thepieces are arranged so that one edge of each overlaps the correspondingedge of the next piece of thel same series or layer.

The pieces are united, preferably by two longitudinal lines of stitches14:, although they may be united by paste or cement if desired. I preferthe stitches however on account of economy of time and labor.

The blank thus formed is embossed to form a hollow rib 15 extendingparallel with the margin of the shank and fore portions and constitutingan inseam stitch-receiving lip, which may be corrugated if desired, asshown in my above mentioned application. I have shown suitable means forembossing the blank in my pending application filed May 21, 1915, SerialNo. 29,503. The blank is preferably embossed before it is trimmed toconvert it into a sole-shaped facing member, and its area is contractedby the embossing operation, as will be seen by a compari- The jointsformed by the overlapping por-' tions of the pieces 12 alternate withthe joints formed by the overlapping portions of the pieces 13, as shownby Fig.' 3, so that the thickened portions formed by said joints arespaced apart, especially at the fore portion; excessive thickness at anyone locality being avoided. I prefer however to increase the width oftheoverlapping portions-of the inner pieces 13 at the shank portion vof thesole, sok that the portion of thevfacing mem-- ber between the lines -mand y-y (Fig. 3)

constitutes an elongated shank portion` of uniformkmaximum thicknessandstiifness, it being` desirable to make the shank portion of thecompleted sole stiffer than the fore and heel portions.

When the inner sole is being'secured to the weltv and upper of a weltedshoe by inseam Stitches passing through theri'b or lip 15, a'

guide on the stitching machine bears on the facing` member of the innersole at the angle formedy by the inner side of'the lip and the. surfaceof the facing member bounded thereby. To prevent said guide fromengaging the exposed edges of the pieces 12 and lifting'said edges, Icanse the exposed edges' at one side of the median line of the solet'oface opposit'ely from the exposed` edges at the other side ofsaid'median line, so that the feeding movement of the soleindicated' bythe arrowsv(Fig. 6) during the stitching operation, will lcause thesaidexposed edges-to slide 'by the guide without being caught andI raisedVthereby. To this end Icut aslit 18 in one end of each piece 12, andinsert the corresponding edge` of the next'piece 'in theI slitsothat twooppositely, facingedgev portions are provided, one at one side,'and theother at the opposite side, of the median 'line of the sole. l

It will be seen that bymaking they facing member of an inner sole ofwaste pieces, thel cost of manufacture is materially reduced, and atthesame time tlie'strength and durability'of the sole and itsstiifnessat the shank portion are greater than would be the case if the facingmember were made from a single layer orv piece of fabric. rlhe jointsformed by the overlapping portions of the piecesextending'transverselyof the sole form a plurality of reinforced portions preventing thefacing member fromstretching crosswise;

Havingdescribed my invention, I claim: 1. An inner sole having a piecedfacing member composed of a plurality of series of pieces ofvwasteflexiblel moldable material, each series forming a layer havingoverlappingfedgesextendingtransversely of the sole and united to form aplurality of reinforced portions preventing the facing member fromstretching'crosswise, the reinforced portions ofone layer alternatingwith those of the next layer topi-event excessive thickness at any yonelocality, the pieces being suitably united andithe member molded to formarib.

2.An innersole having a pieced member composed' of pieces ofy wastematerial having overlapping edges extending transversely of the sole andincluding a plurality of pieces,- eachhavin g a'centralslit in:one ofits transverse edges, and'receivingan edge of theadjoining'piece-whereby the exposed edges of theoverlappingl portions atoneside of the median line ofthe sole are caused to face oppositely-fronrthe exposedfedges at the other side ofsaid line, the'pieces beingsuitably unit'edz` 3; An inner sole havinga pieced member composed of aninner and an outerseries of pieces" of waste'material having overlappingedgesextending: transverselyof the sole, the pieces ofmaterialv at theshank beingy overlapped a1 greater distance toform a relatively 'thickshank portion.

In' testimony whereof I have affixed my signature.
